A gap is left at each apex, and pivoted to track '79 adjacent each gap is a switch 87 having a rearwardly extending arm 88 to which is attached one end of a tension spring 89, the other end of which is fastoned to a pin 90 on the cam drum. By this means, the-switch is yieldingly held closed; the cam drum is reciprocated, because its attachment to slide 48, roller 80, held stationary on standard 83, will cause the cam drum to rotate first in one direction. and then in the other, with brief periods of rest as the roller passes over the fiat surface 91 ot the switches. In Fig. 13, the roller is shown in different positions corresponding to the positions'of the core in Fig. 30, but it will he understood that the roller remains stationary while thecsm drum has motion both oi reciprocation and rotation relative to it, and that this showing ismcrcly for the sake of clearness and convenience.

Tracing out the path of the roller relative to the cam as shown by the arrows in 13, the roller is first in position a; then, as the cam drum is reciprocated, it passes along trecl: 77 over the fiat surface of one switch and under a second, forcing the latter out of the way against the tension of its spring 89 as it passes. Having reached position 01, the direction ofrecipros cation of the cam drum is'reversed, and the roller retraces its path relative to the cam drum, along track 77 and over, the fiat surface of the second switch just referred to and up the track 77 on the other side of the V. It will be clear, from a study of the cam, that, while the cam drum is reciprocated, it impressed upon it a rotative movement, first in one direction, then in the other, then again in the first; but that the rotatiie movement in one direction is in its summation greater than the movement in the other. Expressed somewhat differently, the cam drum has a rotation in one direction, that rotation being accomplished by successive advances and retrogressions, the advances being always greater in amount than the retrogressions. l

007d feeding mechanism (Figs. ,1, 2, 18 to 30, and 51 to 55). I

As will. be seen from Figs. 30 and 51 to 55, the tire is built up by laying-a plurality of goz-irellel cords av diagonally across the out- 4 5 or the core 6 first in one direction and til the desired nunbc.
